What happened was, my team completely disregarded what I said about tilesets being in the same folder. So I had to set them and I didn't want to do them manually in the json files, however the moment I open, Tiled crashes.
Hmm, in general Tiled does not crash when there are missing images, so probably something happens in your scenario that is a bit more special.
Would it be possible for you to share the JSON file that caused Tiled to crash on startup?
Ack, that took me a while but here you go! https://rpgmaker.net/media/content/users/778/locker/Camp.zip
Thanks, that helped a bunch!
It's caused by a tile animation, which is missing a check on whether the frame in the animation is actually pointing to a valid tile.
Fixed possible crash when missing tileset images
This could happen when a map refers to a tileset that uses tile
animations, but the tileset image could not be loaded.
That makes sense, thank you!
